Thanks for the exposition; my inclination regarding a simple module is as follows:

MyModule.pm

package MyModule;
use strict;
use warnings;
use diagnostics;
use Carp;
our $VERSION = 1.08;
sub see_me
{
my $foo = shift;
print "\t\tDo you see this: $foo?\n";
}
1;
__END__
last line of the module needs to be true;
last line of the _file_ need not be true:
0;
